The meeting comes hot on the heels of Yadav's April 3 discussions with district president.
A meeting of all the MLAs and MPs have been called tomorrow by the party president, a party source said here.
Yadav, who is eyeing major role at the Centre after the General Elections, is likely to tighten the noose around some party leaders, sources said.
SP has fixed a target of at least 40 seats (out of 80) in the Lok Sabha polls.
At the meeting of district presidents on April 3, Yadav had taken feedback about party's poll prepardness and was also told about the performance of legislators, ministers and MPs in their respective areas.
SP has declared candidates on 71 Lok Sabha seats.
